o support your investigation, I tried mdb and it says

mdb: target performed exec of /usr/libexec/dovecot/anvil

The last time I built dovecot under OmniOS (quite some time ago), it picked up Linux compatibility functions such as epoll() which were implemented for Linux system call emulation but did not work in dovecot.  So the solution was to force using the more native poll(2) instead.

Hello!

There is some "ifdef" mechanic in there, so you could disable the epoll mechanism with a simple patch and make dovecot use a different approach.

Have a look in  core/m4/ioloop.m4


Ah, there is a configure option --with-ioloop=poll

That is exactly what is done in pkgsrc, they also disable inotify

<snip>
# Explicitly disable epoll/inotify on illumos, dovecot assumes Linux-specific
# implementation details.
CONFIGURE_ARGS.SunOS+= --with-ioloop=poll
CONFIGURE_ARGS.SunOS+= --with-notify=none
